We look at the division of 87833 by 42 
The aim is to understand the frequency of 42 in 87833.

Moving on to step 1:
When dividing 8 by 42, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 42

Advancing to step 2:
If we divide 87 by 42, we get 2 and a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 84 from 87 to get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 42

Let's proceed to step 3:
When dividing 38 by 42, we get 0 with a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 20.0
The remainder is 38 after subtracting 0 from 38.
Fetch the next digit (3) from the dividend, attach it to 38 and continue: 383 / 42

Let's proceed to step 4:
The number 42 fits into 383 9 times, leaving a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 209.0
If we take 378 away from 383, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 42

On to step 5:
If we divide 53 by 42, we get 1 and a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 2091.0
The remainder is 11 after subtracting 42 from 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 6:
42 goes into 110 2 times with a remainder of 26.
Record the quotient 2 as the next digit in the result. 
Result so far: 2091.2
Subtracting 84 from 110 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 7:
42 can be fit into 260 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 2091.26
Subtract 252 from 260 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
42 goes into 80 1 times with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 2091.261
If we subtract 42 from 80, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 9:
If we divide 380 by 42, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 2091.2619
Subtracting 378 from 380 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
The number 42 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 2091.2619
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
200 divided by 42 is 4 with a remainder of 32.
Record the quotient 4 as the next digit in the result. 
Result so far: 2091.261904
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 12:
When dividing 320 by 42, we get 7 with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 2091.2619047
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 13:
The number 42 fits into 260 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 2091.26190476
If we take 252 away from 260, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 2091.26190476 with a balance of 8e-09.
